MEANS FOR PROPELLING AND STEERING SHIPS.

Application filed December 13, 1918.

To all whom -z' may concern:

Be it known that I, CANAAN DECAZEN, a

`subject of the King of Great Britain, and

mechanical engineer, residing at 121 Cherrier iSt., in the cityof Montreal, Province of Quebec, Dominion of Canada, have invented a certain new and useful Invention Relating to Means for Propelling .and Steering Ships; and I do 'hereby declare that the following is a full, clear, and exact description of the same.

The present invention relates to means for propelling and steering ships or the like, and the main object of the inventionis to provide a ship that can be propelled and steered equally well by compressed air, water or any other suitable means.

A further object is to eliminate the use of propellers and rudders thereby lessening accidents which frequently happen when the rudder or the propeller breaks or is damaged.

Another object is to provide means to move a ship in any direction, as well as sidewise if found necessary.

Another object is to entirely handle the ship from the deck or pilot-cabin, which is a considerable improvement on the present method.

The invention will be understood with. the aid of the accompanyingdrawings in which:

Figure 1 is a side elevation of the ship fitted with the invention.

Fig. 2 is a plan view of the ship.

Like numerals of reference indicate corresponding parts in each figure.

In the drawings, 1 is a ship here illustrated as having no stern, both ends being sharpened so that the ship may advance in any direction without altering its speed. Adjacent both ends of the ship, andon opposite sides thereof, are provided openings or holes 2. The two openings on one side of the ship are connected together by a longitudinal pipe 3 and those on the opposite side` are connected or united together by a similar pipe 4.

At some convenient place, in relation to the pipes 3 and 4, is connected a cross pipe 5, and 6 is a pipe preferably disposed at right angles to said pipe 5 and connected thereto at one end and at the other end to an air pump or compressor 7. The pipes 6 and 5 are preferably larger in size than the pipes 3 and 4 and serve as an air tank.

Specification of Letters Patent.

Patented Apr. 2o, 1920.

Serial NO. 266,602.

The pipe 3 is provided with a pair of valves 8 and 11 which are located adjacent one end of pipe 5, while the pipe e' is similarly provided with a pair of Valves 9 and lO which are located adjacent the other end of pipe 5, these valves being controlled from the pilot room as indicated in dotted lines in Fig. l. These valves if operated may change the speed of the ship, alter its course, steer the ship, or cause the ship to move sidewise.

For instance if the valves 8 and 9 are closed and the valves 10 and 11 are opened, the ship will move in the direction of the arrows; on the other hand, if the direction in which the ship moves must be altered, the valves 11 and 10 must be closed and the valves 8 and 9 opened. To steer the ship, the pressure in one of the valves must be reduced or cut-off, as for example: if the ship must be turned, by keeping the valve 10 opened and the valve 11 closed, the ship will be swung around. If it is necessary to speed-up the operation, the valve 8 couldalso be opened. To move the ship sidewise the valves 8 and 11 or the valves 9 and 10 must be opened which will give the ship a lateral impulse.

The valves. as said above. should preferably be operated from the deck or pilot-room and this can be done electrically, mechanicallv. or otherwise.

Furthermore the drawings disclose a pilotroom at each end of the upper deck of the ship, from which it is possible to operate the valves.

The air compressor is here illustrated as actuated by an engine 12, but it will be readily understood that it can be actuated by anv other suitable means.

It will also be readily understood that the ship may also be moved by water or gas under pressure.

The air on leaving the compressor enters the tank formed by pipes 6 and 5 and from there is directed into the pipes 3 and A. The compressed air comes out through the openings 2 in the form of a j et and when it comes into contact with a resisting body such as water. it is evident that an impulse will be given to the ship. The more pressure there is, the more speed will be obtained.

This invention obviouslv has many advantages over the present method of propelling boats or ships. It eliminates the the boat at opposite sides of and in spaced,

parallel relation to its longitudinal axis; said pipes extending uninterruptedly from stem to stern of the boat, and each of them opening at its opposite ends through the hull w of the boat below the water line at stem and Y stern; a cross-pipe connecting the longitudinal pipes intermediate their ends; and means for forcing fluid under pressure through the cross-pipe into and through either or both longitudinal pipes alternatively and in either direction into the sea in jet iorm, so as to' both steer and propel the boat solely by the direct action of such fluid against the water.

2. A boat provided with propelling and steering mechanism which consists solely of a pair of pipes disposed symmetrically of the boat at opposite sides of and in spaced, parallel relation to its longitudinal axis; said pipes extending uninterruptedly from stem to stern of the boat, and each of them opening at its opposite ends through the hull of the boat below the water line at stem and stern; a tank situated between said pipes and communicating with the same at a point intermediate their ends, said tank adapted to constantly contain fluid under pressure; and a series of valves for controlling the passage from the tank selectively into and through either or both of said pipes and in either direction into the sea in jet form; so as to both steer and propel the boat solely by the direct action of such fluid against the water.

Signed at Montreal, Canada, this Qnd'day of December 1918.
